Bose has upgraded its SoundTouch series to version 3 and added the new entry level SoundTouch 10 to the existing 20 and 30. Bose has implemented a new dual band wifi platform with better performance and now supports b/g/n. Bluetooth has been added, which is fine but AirPlay has been removed for some strange reason. So this is obviously a potential deal breaker if you use AirPlay. The previous version of SoundTouch series will continue to have AirPlay support.
The new SoundTouch 10 is a direct competitor to Sonos Play 1 and replaces the previous SoundTouch Portable. It has (like its bigger brothers) support for Spotify Connect and Bluetooth. Bose also has support for internet radio and Deezer through their own app. It also has USB and AUX inputs for external sources. SoundTouch 10 costs 199$/179£ and comes in white and black.
